It's okay... Serves its purpose. Some reviewers have stated there's a strong plastic smell during the first few uses; however I can't say I noticed.
The stitching could be a little more robust, mine has already started to come lose at one side of the bottle flap. I believe this may be the result of a trade off between; a softer fabric or a hardwearing fabric. Nothing that can't be easily fixed.
All in all, it's satisfied my requirements.
